" T ai'lwlzom it may concern:

' Be it known that I, DANIEL 'W. MGNEIL, a citizen of the United Statesof America, and resident of Cincinnati, county of Hamilton, and State ofOhio, have invented certain new and useful Improvements in FlushMechanism for Closets, of which the fol lowing is a specification.

This invention relates to flush mechanism for closets, and has for anobject to produce a s'simple and reliable seat actuated flush valve andvalve operating mechanisms of plication and forming improvedconstruction. This and other objects I'attain by means of apparatusembodying the features herein described and illustrated.

In the drawings accompanying this apa part-thereof, Fig. 1. is anelevation of a closet embodying my invention, portions being shown insection and portions being broken away for convenience of illustration.Fig. 2 is a sectional view of a portion of the valve operatingmechanism, which forms a part of my invention; Fig, L is a sectionalview of an improved form of flush valve which forms a detail of myinvention.

Referring to the drawings :-The apparatus illustrated, comprises aball-float or flush valve 1, which is located in a flush tank 5, a seatoperated mechanism for unseating the Valve 4, and a stop valve 6 whichis actuated by the seat operated mechanism, and is adapted to shut offthe flow, of water from the tank 5 while the operating pressure ismaintained on the seat 7 and while the valve is open or unseated. Theflush valve 4 illustrated consists of a hollowballshaped disk, which ispreferably made of rubber and 1s provided on one s1de with a lug 8, 1nwhich a metal ferrule 9 is located.

,Th'eferrule is'provided with a threaded and I longitudinally extendingopening, which registers with apertures provided 1n the lug 8. A stem orguide rod 10 for the ball 4 is threaded at its lower. end and is adaptedto be screwed into, the ferrule 9. A contact rod 11 is threaded at itsupper end and is screwed into the lower end of the ferrule 9.

This rod extends from the ferrule down= wardly through .the interior ofthe .ball' 1 and projects a short distance beyond the surface of theball through an aperture 12. The stem or guide rodlO is secured in placein the tank 5 in any suitable manner, so that it will permit the ball tomove up and down freely, but will to some extent guide its movements.The ball 4 is adapted to seat on a flange of a discharge port 13,provided in the bottom of the tank 5, and in this manner cut offcommunication between the tank 5 and a flush pipe 14, which extendsdownwardly from the port 13 and communicates with the flush passages ofthe porcelain bowl 15 of the closet.

A release rod 16 extends ,u,pwardly through the piping let; and isprovided at its upper end with a' cup-shaped seat '17, which is adaptedto contact with the contact rod 11 of the ball 4 and to raise'theball-from its seat, for the purpose 'of opening the port 13.

The ball 4 is held to its seatby the unbalanced water pressure, but assoonas it is unseated, it is exposed on all sides to water pressure, andconsequently floats upwardly and fully opens-the port 13. The. ball willnot close the port until almost all of the water is discharged from thetankand the ball has moved adjacent to the port 13. It is then carriedby the flow of water, through the port, to its seat and the unbalancedcondition is reestablished. The release rod '16 extends downwardlythrough the piping 14: and its lower end seats on the valve 6, which islocated in a housing 18, secured to'the lower end of the piping 14. Thehousing 18 is provided with a; discharge port 19, which communicatesthrough suitable piping 20 with the flush passages of the bowl 15. Thevalve 6 is mounted on a rod 21 and is adapted to'seat on an annularflange or seat 22, provided on the housing 18, for the purpose ofclosing communication between the piping 14 and the housing 18, andconsequently between the flush tank 5 and the flush passages of the bowl15. The lower end of the housing 118 is closed by-a'screwcap 23, throughwhich the rod 21 projects, and which is provided withan integrallyformed annular flange 24:, in which a suitable packing 24' for the rod21 is located.-

.A- depending sleeve 25. is screwed, or otherwise secured, to the flange24 and forms a guide for a cap-nut 26, which is screwed thisarrangement, the packing 24: is maintained tight by the tension of thespring 27, and the bushlng 28 forms a guide for the rod 21.' The cap-nut26 is adapted to contact with the lever 29. ,A disk 32 is secured on therod 21 and is so located within the housing 18, that it will seat on aflange pro vided on the cap 23 around the rod 21, when the rod is movedto its lowest position by the tension of the spring 27.

The valve 6 illustrated, consists ofa valve I disk providedv with meansfor securing a washer in-place, and provided with an annular flange 33,whichis adapted to fit over '0! cap the upper end of the-rod 21, and issecured in place on the rod by means of what may be termed a lost-motionconnection. The lost-motion connection consists of a pin 34:, whichextends diametrically across the flange 33 and is located within alongitudinally extending slot 35, provided in the rod 21 near its-upperend. The valve 6 is yieldingly held inposition on the rod 21 by a coilspring 36, which surrounds the upper end of the rod and the flange 33and yieldingly forces the valve upwardly, so that the pin 34= isnormally held'in contact with the upper end of the slot 35 With thisarrangement, the lost-motion connection is self-adjusting. a

The operation of the ap aratus is as follows: When the seat- 7 isepressed against the bowl 153, the rod 21 is raised through the agencyof'the lever 29, so that it moves the valve. 6 against its seat 22 andcauses the release rod 16 to move upwardly andunseat' the valve 4. Thisopens communication between the tank 5 and the flush pipe, 14, but doesnot permit of a flow of water to the'bowl 1 5, since the valve 6 closescommunication between the piping 14 and the housing 18. As soon as thedepressing force is removed from the seat 7, the rod 21 is forceddownwardly by the pressure of the s rin 27, so thatjthe va1ve.6 isunseated, t e (1151; 32 seated, and so that the seat 7 is raised to thenormal or inoperative position. The 'unseating of the valve 6 openscommunication between the tank- 5 and the bowl 15 and causes a flow ofwater from the tank through the flush passages of the bo'w1.

Byemploying. the self-adjusting lost-motion connectlon-between the valve6 and the rod 21, the rod 21 may be raised a considering leakage aroundthe rod and is eifective when the rod 2]. is forced to its lowestposition. The washers on the valve 6 and on the valve disk 32 may berenewed by simply removing the cap 23 and withdrawing the-valve from thehousing 18. The tension of a fixture '38; With this arrangement, the

flush pipe 4 andtthe'housing 18 are rendered more rigid and the housingis prevented from turning out of alinement after the closet isinstalled.
